db_sync in zz 0.70

["17.hzV.tRL.478" <opt@xxxxx>]

hi
i really cant get version 0.70 to 'run' because
the subroutine &ZigZag::db_sync cant be found ...
so, zz starts up but
the error comes up as soon as i want to insert a cell for exaomple.
grepping the Zigzag.pm file, i cant find any db_sync sub,
whats wrong herE?
tks,os
